The head honchos of Tamil Nadu and Kerala have been collaborating on keeping the alarmists at bay over the Mullaperiyar Dam issue. The States are at loggerheads over the permissible height of water storage in the dam with Kerala wishing to build a new dam and take the 125-year-old dam out of the equation even as TN insists on its water rights from a perennial treaty. Alarmists are having a field day spreading rumours of impending disaster even as the opposition AIADMK is whipping up a campaign on TN’s water rights. The CMs are seeing reason in a tense scenario. The Supreme Court may have said the dam is safe and water can be stored upto 142 feet. Taking into consideration the fear of Keralites living below the dam in Idukki district, TN is keeping the water level only at 139 feet or less. The irrigation and drinking water needs of TN’s southern districts may be great but they will not be met by endangering the safety of a dam that stops a west-flowing river to take the water eastwards through giant pipes from the dam built by British engineer Penniquick who pledged his wife’s jewels to complete the work on his limestone masterpiece that has stood the test of time.
